Setting Software Instrument Channel Parameters
The following parameters are specific to instrument channel strips.
MIDI Channel
This parameter sets the MIDI channel used by the software instrument.
Value as
This switches the channel strip displays (meters and other parameters) between decibel
(dB) and numerical (Num) values. The decibel display is the default.
Setting External MIDI Channel Parameters
The following parameters are specific to External MIDI channel strips.
MIDI Channel and Port Connection
The Port parameter defines the physical MIDI output that data is sent to. Your MIDI
sound module is connected to this MIDI output connector.
The MIDI channel is set with the Channel parameter. This defines the channel used for
MIDI output by the instrument track, allowing your “real” instrument to receive the
data.
Setting the MIDI Channel: Multi Instruments
You can also alter the MIDI channel of an external MIDI instrument part by choosing
another sub-channel of the current multi instrument.
A sub-channel is one of 16 possible MIDI channels or parts that can be played by a
multi instrument object. It goes without saying that the external MIDI synthesizer
(represented by the multi instrument object) needs to be capable of playing on more
than one MIDI channel for sub-channel selection to be useful.
